"Killing the government" is a euphemism. He's talking about killing government employees who implement things you don't like.

What you're ultimately talking about is terrorism - if you're a government employee, don't do bad things* or we might "predict" your death. The choice they're presenting seems to be either bad, violent actors in government, or bad, violent lynch mobs.

*Where "bad things" might be anything from "invading Iraq" to "free healthcare".
